Specification of Letters Patent.

Patented Aug. 7, 1917.

Application filed October 28, 1915, Serial No. 58,330. Renewed December 23, 1916. Serial No. 138,675,

To all whom it may concern:

Be it known that I, TILLIAM H. OLM' STEAD, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Shade-Roller-Pin-Setting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a pintle setting and driving device by which pintles or pins can be mounted in the ends of a curtain shade roller or similar structure.

The objects of my invention are, first, to provide a device by which a curtain shade roller may be firmly held and a pintle or pin accurately driven or mounted in the end of the curtain shade roller; second, to provide a device of the above type which may be expeditiously operated to properly position a pintle in the end of a roller whereby it will afford an accurate arbor or trunnion for the curtain shade roller; third, to furnish a device of the above type with ex changeable and adjustable driving heads which permit of pintles or pins being prop erly centered in rollers or structures of various diameters, and fourth, to provide a simple, durable and inexpensive pintle setting device which may be used upon a bench and easily manipulated by an operator to drive pintles or pins into the ends of ourtain shade rollers.

The mechanical construction by which I attain the above and other objects will be hereinafter s ecifically described and then claimed, and reference will now be had to the drawing, wherein- Figurerl is a perspective view of a device in accordance with my invention;

Fig. 2 is an end view of a detached or pin carrying head;

Fig. 3 is an enlarged longitudinal sectional view of a portion of the device illustrating a modification of my invention; and

Fig. 4 is a longitudinal sectional View of a portion of the device shown in Fig. 1.

In the drawing, 1 denotes an oblong bed plate having the ends thereof provided with apertured lugs 2 whereby it may be secured to a bench or suitable support by screws, bolts or similar fastening means. On one pintle end of the bed plate is an oblong support 3 provided with a seat 1 Vshape in cross section and adapted to accommodate a similarly shaped liner 5 which may be secured to the seat 41 by a screw 6 or similar fastening means. The liner 5 afiords a seat for the end of a'curtain shade roller and to hold the end of the curtain shade roller in position while a pintle or pin is being driven in the end thereof, a clamping member 7 is pivoted upon a pin 8 mounted transversely of bearings 9, carried by the support 3. The clamping member 7 has a curved serrated or otherwise roughened gripping surface 10 and it is through the medium of a lever or handle 11 forming part of sald clamping member that said member can be shifted into engagement with a curtain shade roller and a suiiicient pressure brought to bear to firmly hold the curtain shade roller while a pintle or pin is being driven therein.

On the opposite end of the bed plate 1 is a longitudinally disposed bearing or guide 12 for a reciprocable solid plunger 13. The

forward end of the plunger 13 has a socket 141 with the walls thereof screw threaded to receive the stem or stud 15 of a circular head 16. The circular head 16 is knurled to facilitate attaching the head to the plunger 13 and a washer or gasket 17 is interposed between said head and the end of the plunger whereby the head may be properly positioned relative to said plunger. The circular head 16 has a concentric pocket 18 and an annular recess 19 to receive the outer end 20 of a pintle or pin 21, said pintle or pin having the usual collar 22 adapted to limit the inward movement of the pintle or pin when driven into the end of the curtain shade roller. The recess 19 provides clearance for the collar 22 and the pintle or pin is firmly held by the head 16 while being driven into the end of the curtain shade roller.

The opposite end of the plunger 13 is bifurcated or slotted, as at 23, to receive a lever 24 loosely connected to the plunger by a transverse pin 25 passing through a slot 26 in said lever. The lower end of the lever 24: extends through a slot or opening 27 in the bed plate 1 and is looselv mounted upon a transverse pivot pin 28 carried bv depending parallel lugs or hangers 29 of the bed plate 1. When the bed plate is secured to a work bench the bench is cut away to provide clearance for the lugs or hangers. The lever 24 permits of the plunger 13 being reciprocated in the bearing or guide 12 and there is suflieient leverage for forcing the pintle or pin 21 into the end of the curtain shade roller held upon the liner 5 by the clamping member 7. It is thepresent practice to provide the end of a curtain shade roller with a metallic cap having a concentric pierced opening or indentation which properly centers the pintle or pin and by placing the pintle or pin in the head 16, the plunger 13 can be shifted to drive the pintle or pin through the pierced cap or indentation thereof into the end of the cur tain shade roller and this operation is performed without any danger of the curtain shade roller slipping or splitting.

In Fig. 3 of the drawings, there is illustrated a slight modification of my invention, wherein a tubular plunger 30 is used in lieu of the solid plunger 13, said tubular plunger receiving the stem or stud 31 of a driving head 32 which is locked relative to the tubular plungerBO by a set screw 33 in the forward end of the plunger. The head 32, as best shown in Figs. 2 and 3, has a plurality of pockets and recesses 34: positioned at various distances from the center or longitudinal axis of the head 39. whereby the head 32 may be adjusted in the plunger 30 to support pintles or pins in proper relation to curtain shade rollers of various diameters. With this type of pintle carrying head it is unnecessary to use liners in connection with the curtain shade roller holder.

In the manufacture of curtain shade rollers, it is the practice to take a long red or pole and saw the same into desired lengths. Such sawing leaves ragged or splintered ends, therefore I have provided a side of the support 3 with a finishing device in the form of a conical socket member 35 having knurled, serrated or otherwise roughened walls 36 adapted to file and remove ragged or splintered edges on the end of a curtain shade roller when said roller is placed in the socket member and rotated therein. This operation can be performed prior to placing the usual metallic cap upon the end of the curtain shade roller.

Insomuch that a driving head can be properly positioned relative to a curtain shade roller on the support 3, it is possible to accurately drive apintle or pin concentric of the end of a curtain shade roller and thereby insure proper rotation of the curtain shade roller when mounted in the usual window frame bracket. Instead of a hammer blow whichhas a tendency to split or injure the end of a curtain shade roller, the plunger 13 has a steady and unwavering movement that forces a pintle or pin into the end of a curtain shade roller and properly sets the same.

The preferred embodiments of my invention have been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is 1. A device of the type described comprising a horizontally disposed support, means carried thereby adapted to hold a curtain shade roller on said support, a reciprocable plunger at one end of said support adapted for movement toward the curtain shade roller held on said support to force a pintle in the curtain shade roller, and a pintle carrying head having a plurality of sockets and connected to said plunger for adjustment to place the pintle in the longitudinal axis of the curtain shade roller held on said support. a

2. A device of the type described, comprising a horizontally disposed support, means carried thereby arranged for clamping a curtain shade roller on said support, a reciprocable plunger at one end of said support, an adjustable pintle carrying head detachably connected to said plunger and having a plurality of sockets, and a lever pivoted below said support and connected to said plunger above said support to facilitate moving the same toward and from said support.

3. A device of the type described coinprlsing a support, a liner detachably connected thereto and adapted for supporting a curtain shade roller, a clamping member carried by said support and adapted to hold the curtain shade roller upon said liner, a reciprocable plunger movable to and from said support, means for. reciprocating said plunger, and means carried by said plunger adapted to hold a pintle whereby the pintle may be forced into the end of the curtain shade roller.

4}. A device of the type described, comprising a support, a liner detachably connected thereto, a pivoted clamping member supported by said support and adapted to hold a curtain shade roller upon said liner, a recipro'cable plunger at one end of said support, a pintle carrying head forming part of said plunger, and means connected to said plunger to facilitate moving said plunger to and from said support.
